Q:scaffold pierving help please=] ???!!?
Several people have told me it hurts about the same. I do not have one, sorry couldn't be more help than that.
Q:A painter and a scaffold?
First of units, no answer. Second of all...according to OSHA (Occupation Safety and Health Administration), NO ONE can walk on a scaffold beam outside the support ropes OR SET ANY OBJECT DOWN outside the support ropes. Hence the answers for both questions are 1 meter. It doesn't matter what a calculation will yield...NO ONE can walk on the beam outside the support ropes safely. Even if a torque balance yields that it will not put the ropes in compression and buckle still isn't considered to be safe by OSHA if the painter is outside the ropes.
